  a- Standards, shown in black, are established by API, SAE and others. Ranges, shown in teal, represent the high and low data ranges for the major's 5W-30 API SM GF-4.

  b-Test Method used for metal analysis is ASTM ASTM D5185.

  c- ASTM D5185-09 Reproducibility by Element.

  d- The specification of 15 max is expressed in two significant figures and therefore this average of the two results meets specification.

Note: Should a lubricant manufacturer have independent test data (bench or engine) that shows its lubricant offers higher quality and/or performance than others, we welcome this information and remain prepared to publish it on this website if and when provided.
